Sublime Text is a fast, proprietary text and code editor known for quick start-up, multiple selections and a command palette. Open-source options range from lightweight editors that feel similar to full IDE-style environments.
Every tool below is under an OSI-approved licence (MIT, GPL, MPL-2.0 or Apache-2.0), checked against its repository. Note that Microsoft's own Visual Studio Code build ships under a Microsoft product licence, so VSCodium is listed instead as the freely licensed build of the MIT-licensed source.
Licences checked against each repository on November 7, 2026.

Quick answers to common questions
No, it is proprietary software.
Lite XL is closest in feel: a small, fast editor with a plugin system. Zed and Helix are good options if you prefer speed with modern features.
The Code - OSS source repository is MIT-licensed, but Microsoft's Visual Studio Code distribution has its own product licence. VSCodium provides MIT-licensed builds.
Helix is built around them. Zed and VSCodium also support them.
Not directly. Most have their own plugin systems, so you will need equivalents.
List it on TechLogHub and we'll review it for this page.
